ABOUT Lariam Tablets

What is Lariam?

Lariam is an antimalarial drug for the prevention and treatment of a particular type of malaria called falciparum malaria. It is a relatively fatal form of malaria caused by parasite strains like P.falciparum and P.vivax, which are mostly resistant to other commonly used antimalarial drugs like chloroquine. 

Lariam is available in 250 mg tablet form. 


How does Lariam work?

The active ingredient in the Lariam tablets is Mefloquine hydrochloride, a preventive drug against malaria. Malaria is fatal diseases caused by a parasite, plasmodium which is transferred to the human body in result of a mosquito bite. Plasmodium is injected into the bloodstream during a bite from an infected mosquito. The parasites travel to the liver and reproduce they're resulting in the disease. 

Lariam protects the body from malaria by killing the parasites after its release from the liver into the bloodstream and interferes its growth in the red blood cells. 


How do I take Lariam?

The recommended preventive dose of Lariam is one tablet of 250mg per week. It should be taken on the same day of the week, depending on the duration of stay in the malarial region. 

  • Start taking the tablet one week before arrival to the malarial area (prophylactic treatment)
  • Take one tablet every week throughout your stay
  • Continue taking the pill for four weeks after leaving the area (to inhibit the reproduction of parasites, if you have infected)

The dose to be taken is adjusted according to the bodyweight of the person. 

  • For adults weighing 45kg or more, the dose is one tablet per week. 
  • For adults or children weighing 31 to 45kg, the treatment is three-quarters of Lariam tablets.
  • Adults or children weighing range of 20 to 30kg should take half a pill once a week.  
  • Children weighing from 5 to 19kg should take a quarter of a tablet. 

It is advisable to consult your doctor or pharmacist before taking the tablet to have a proper dose adjustment. Lariam should be taken with a glass of water or milk, preferably not on an empty stomach. 


What if I miss a dose of Lariam?

If you miss a dose of Lariam, then take it as soon as you remember to take it. Continue taking the next doses weekly from the day on which you have taken the missed dose. Avoid taking more than one tablet in a week. 


Who should not take Lariam?

People with the following disorders must consult their doctor to find out whether the Lariam is safe for them or not if they have

  • Heart disease
  • Epilepsy
  • Liver disease
  • Diabetes 
  • Blood clotting problem
  • Patients taking blood-thinning medicines such as warfarin, Coumadin, Jantoven etc
  • People who have had blackwater fever, a severe malarial complication. 

Can I take Lariam during pregnancy or breastfeeding?

Pregnancy

The pregnant women are more at the stake of having malaria, so it is better to avoid the malarial region as a precautionary measure. The risk of stillbirth, miscarriage, and neonatal death increases if the expecting mother suffers from malaria. If it is unavoidable to go, then these women should use repellents to avoid mosquito bites. 

Regarding the safety of Lariam in pregnant women, it has not been completely established. However, the use of Lariam can be allowed by the doctors when there is increased risk of medical problems due to malaria than any other threat that is associated with Lariam intake. As the safety of the drug has not been completely developed, women should use contraceptives to avoid pregnancy when they are on Lariam therapy and up to three months after stopping Lariam intake. But if you have already been pregnant, then there is no reason to terminate the pregnancy. 

Breastfeeding

Although a minimal amount of drug passes into the breast milk and is not dangerous for the feeding infant, it is better to take your doctors' advice if you are a nursing mother. A nursing mother should only take Lariam if its benefits outweigh any risk that is associated with the infant on breastmilk. 

It is vital to consider that the amount of medicine passed in mothers' milk is not enough to protect the baby against malaria. In case of need, the baby should be given its dose of Lariam to be protected against disease. Whereas if both mother and infant are taking Lariam, then the amount of drug passed in the infant should be closely monitored particularly in low weight babies.


Warnings and Precautions

Specific precautionary measures should be taken if you are suffering from any underlying health condition and should be consulted in detail with your doctor. Some of the conditions that can develop and maybe life-threatening are

Anaemia

Lariam can cause a decrease in red blood cells to count. If the symptoms of low blood count like shortness of breath, feeling tired or pale skin appears than contact your health service provider.

Dizziness

In some patients' dizziness and loss of, balance can occur after the use of Lariam. If you are suffering from any such problem, then do not perform the tasks that require alertness like driving or operating machinery until you feel fit to do so. 

Heart Problems

If you suffer from any kind of palpitation or irregular heartbeat, contact the medical help as soon as possible to avoid any threatening situations.

Dose adjustment in some cases

The dose of Lariam has to adjust in patients who are suffering from kidney or liver disorders. In such patients, the blood levels of the drug can raise than usual and need a reduction or adjustment in the standard dose. Patients having kidney and liver disorders should not take medicine without consulting a doctor or pharmacist.  

Mental Problems

Some psychiatric and nerve problems can occur in some persons taking Lariam. In some cases, these effects sustain for 6 months, 1 year or sometimes remain permanently after the treatment with Lariam. Immediately consult the doctor if you are experiencing any of these issues. 

Epilepsy

Lariam can increase the chances of seizure attacks in persons having a history of epilepsy. These patients should not use Larium to protect malaria and only use it for treatment when benefits are more than risks. 


Can I take Lariam with other medicines?

It is essential to talk to your doctor or pharmacist about any other medication that you are taking before starting Lariam. Particular medicines can have a drug interaction when taken in combination with Lariam. Similarly, it is equally important to check the drug interaction between Lariam and to start any new medicine.
